Begin by connecting pin 85 of the relay to a clean ground point on the vehicle chassis or the negative terminal of the battery. Then connect pin 86 to the ignition switch wire — this is the wire that ...

Electromechanical components such as relays and switches often must undergo endurance tests that verify their reliability and safety. Regulatory standards typically have compliance criteria that ...

As an electric motor’s rotor turns in close proximity to the motor windings, a bucking voltage or back electromotive force (EMF) is generated. The back EMF (BEMF) generated across the start winding is ...

I once new a way of checking for an open relay by telneting into port 25 on the smtp server. I have since forgotten. Can anyone reffresh my memory as I dont want to leave my mail server open to ...

The objective of protective relays and protective schemes is to protect electrical equipment such as transformers, lines, cables, bus bars, etc. during abnormal system conditions. Hence, protective ...

Programmable logic controllers (PLCs) and computer-based controllers are great for handling logic and data-collection tasks for industrial controls. But when it comes to driving motors, heaters, ...

RF coaxial SPDT relays address signal-routing applications that demand a combination of high frequency, high power, and excellent RF performance. What role does an SPDT relay play in test applications ...
